Getting Started with Talend Open Studio for Data Integration

By: Jonathan Bowen

Overview of this book

Talend Open Studio for Data Integration (TOS) is an open source graphical development environment for creating custom integrations between systems. It comes with over 600 pre-built connectors that make it quick and easy to connect databases, transform files, load data, move, copy and rename files and connect individual components in order to define complex integration processes. "Getting Started with Talend Open Studio for Data Integration" illustrates common uses and scenarios in a simple, practical manner and, building on knowledge as the book progresses, works towards more complex integration solutions. TOS is a code generator and so does a lot of the "heavy lifting"ù for you. As such, it is a suitable tool for experienced developers and non-developers alike. You'll start by learning how to construct some common integrations tasks ñ transforming files and extracting data from a database, for example. These building blocks form a "toolkit"ù of techniques that you will learn how to apply in many different situations. By the end of the book, once complex integrations will appear easy and you will be your organization's integration expert! Best of all, TOS makes integrating systems fun!

Managing local files

In this section we will look at local file operations. We'll cover common operations that all computer users will be familiar with—copying, deleting, moving, renaming, and archiving files. We'll also look at some not-so-common techniques, such as timestamping files, checking for the existence of a file, and listing the files in a directory.

Copying files

For our first file job, let's look at a simple file copy process. We will create a job that looks in a specific directory for a file and copies it to another location.

Let's do some setup first (we can use this for all of the file examples). In your project directory, create a new folder and name it FileManagement. Within this folder, create two more folders and name them Source and Target. In the Source directory, drop a simple text file and name it original.txt. Now let's create our job:

  1. Create a new folder in Repository and name it Chapter6.

  2. Create a new job within the Chapter6 directory and name it FileCopy.

  3. In the Palette...
